Rubikʼs cube

A rubikʼs cube is an interesting puzzle invented by erno rubik in the early 20 century. It has over 4 quadrillion combinations possible so it is very hard to solve. Luckily there are techniques that are used to make solving one easy. The world record for speedcubing is less than 10 seconds. My personal record is 45 seconds.
There are 3 techniques and the more efficient ones are much harder but allow speedcubing to be possible. There are also variations on the 3x3 like the Rubikʼs Revenge, a 4x4 and the Professors Cube, a 5x5. Eastsheen has developed 6x6 and 7x7s.
They are exciting puzzles and solving one is a feat that almost everyone takes to great surprise and makes them believe you are a genius, when really, the technique for solving one is quite simple indeed.
